Title: Why Can an Electron Absorb a Photon?
Post by: talanum1 on 24/10/2022 15:42:15
In my model a particle is a copy of all of 2D space, compactified into a Riemann Sphere. For an electron to absorb a photon all that is needed is that the two Riemann Spheres must merge. They can do that since the Riemann Sphere (RS) contains a singular point at it's north pole. The resulting electron's RS is therefore more compact than before the interaction.

"Why Can an Electron Absorb a Photon?"
In general, it can't.

What is the name for the spheroids that hang between a bull's legs?

Or the material that exudes from its anus?

"Why Can an Electron Absorb a Photon?"
In general, it can't.

This is not what observation shows.

Would you like to bet on that?

We can certainly alter the state of an electron by adding electromagnetic energy. I suspect the OP has adopted a naive model, and the simplistic answer to the question is "because it has spin and charge". The problem is that he wants to make the model more complicated.

An electron, on it's own, can scatter a photon.
And there will be some change in the photon's energy.
But it will not be absorbed.

So the answer to "Why Can an Electron Absorb a Photon?"
Is still
In general, it can't.

Every light bulb says: electrons can emit photons. Every television tube says: electrons absorbs photons.

Every light bulb says: electrons can emit photons. Every television tube says: electrons absorbs photons.
Light bulbs don't actually talk.

Basic physics says that EM radiation is emitted by accelerated charges and an electron can't accelerate on its own.

One explanation for an electron accelerated by a EM field is because it absorbed photons.

One explanation for an electron accelerated by a EM field is because it absorbed photons.

Q What happens next?
A The photon is re-emitted

This process is called scattering.
Like I said earlier


An electron, on it's own, can scatter a photon.
And there will be some change in the photon's energy.
But it will not be absorbed.
